I see something similar, now in 2024. I've not participated in ESPP in years, so I'm less familiar with the cost basis adjustment process and what manual calculations to attempt (to find the correct number).
Before filing my 2024 return, I'd noticed that my amount due decreased when I adjusted my ESPP cost basis per the TT guided steps. This made sense, as I was trying to avoid the double taxation of the 15% discount taxed as ordinary income and the artificially low cost basis shown on the 1099-B (adjusted with Form 3922). However, when I filed, the amount due returned to the original, higher number (equal to before I did the basis adjustment).
Just tonight, with TT on the phone, I went through an amended return, following the same cost basis adjustment. We went through filing with TT showing that I was owed a refund (equal to an amount matching the cost basis adjustments). However, once again upon submitting I see the PDF shows I'm owed $0.00 (matching the behavior from when I initially filed).
Anyone else tracked this down? In my case, it was a disqualifying disposition ... and I need to look at whether this relates to the fluctuating numbers throughout the TT filing process.
