W2 doesn't include all disqualified ISO as compensation - needs correction?

[bluecloud33]

We accidentally sold an ISO purchase from 2021 a few days too early, so it became a disqualified ISO and counts as compensation. The company didn't catch this - they only listed disqualified ISO exercised/sold in 2022 (same-day sale) on the W2. 

Turbotax allowed me to report that some disqualified ISO sales weren't included in the W2, and the software added it to the 1040 correctly. Can I just go with what Turbotax did, or should I require that the company reissue the W2 so that it reflects ALL disqualified ISOs on the 2022 tax return? Which is more likely to cause an audit?

says, yes, the W-2 should be corrected.  However, you can continue your tax returns to the point just prior to e-file so that you know whether you will owe the IRS and/or your state and, if so, prepare extension form(s) with the amount(s) due should the company be slow or obstructive in making the correction.

Also, do read https://www.irs.gov/taxtopics/tc154 which gives the steps to take in getting a corrected W-2.
