The following is a very incomplete answer because it has a list but not with each described. I hope somebody can post an answer with each one described.
There is an article here https://blogs.timesofisrael.com/many-rabbis-agree-that-ezra-changed-the-torah-text/#_ftn4
That says this.. It lists the references. Then after, it only describes one or two, not all.
"The eighteen alterations of Scripture, listed in the classic work Ochlah W’Ochlah,[4] are as follows: (1) Genesis 18:22, (2) Numbers 11:15, (3 and 4) Numbers 12:12, (5) I Samuel 3:13, (6) II Samuel 16:12, (7) I Kings 12:16, (8) II Chronicles 10:16, (9) Jeremiah 2:11, (10) Ezekiel 8:17, (11) Hosea 4:7, (12) Habakkuk 1:11, (13) Zechariah 2:12, (14) Malachi 1:13, (15) Psalms 106:20, (16) Job 7:20, (17) Job 32:3, and (18) Lamentations 3:19."
(there are two changes in Numbers 12:12)
That article doesn't state the details of each change though.
This article by avrohom lieberman may be of interest but doesn't detail each one either http://www.zen76171.zen.co.uk/tikuneisofrimarticle.pdf He mentions other ideas e.g. that there are only a few, or that there's about 30. Avrohom Lieberman's article mentions ideas such as that the emendations go back to when the book was first written e.g. moses made the emendations in the 5 books(no doubt avrohom lieberman assumes/holds to mosaic authorship). Ginsberg lists about 134 but that article by avrohom lieberman says that modern masoretic scholarship puts it at less than Ginsberg lists. Ginsberg's list is mentioned https://levendwater.org/companion/append32.html and http://www.oocities.org/hebrew_roots/html/hr-2-1-02.html
The list mentioned in Avrohom Lieberman's article also doesn't detail each one, and suggests there may be some variation in the list, as he says the listing he gives is "more of less, the classical 18 tikkunei soferim".
I notice that when comparing the small list, the 18, compared with Ginsberg's list.. It's not like Ginseberg's list is all of the 18 + more. Infact it looks to me like Ginsberg's list includes none of the 18. So the lists may be different in nature. According to the two links I gave for Ginsberg's list, Ginsberg's list is for changes of the tetragrammaton to Adonai(with kamatz).
The 18 may be changes other than that e.g. that "times of israel" link mentions one of the 18.
"The original wording in Zechariah 2:12 has God saying that “whoever
touches you [Israel] touches the apple of my eye.” The metaphor of
someone poking a finger in God’s eye suggests that God has an eye and
can be harmed. It was replaced to “his eye,” implying that whoever
touches Israel will be punished so severely that it is as if he
damaged his own eye."
So, that, from the 18, is not a change of Tetragrammaton to Adonai(with kamatz), and likely all the 18 are not. Whereas the Ginsberg list , according to those two links, are all changes of Tetragrammaton to Adonai(with kamatz).
Regarding the 18, or perhaps even generally any change https://www.encyclopedia.com/religion/encyclopedias-almanacs-transcripts-and-maps/tikkun-soferim "Not Everyone Agreed That Words Were Substituted in the Torah"
Hopefully somebody can post a better answer, that'd be one that lists the details of each one of the 18.
