Just FYI, our return was nearly finished when I encountered this (so I know quite well what our 2024 gross income level is). I was doing capital gains stuff last because I thought I needed to enter more than 100 transactions by hand (our 1099-B had no document ID and the bank could/would not provide one!!), but I learned you can sometimes get away with entering a summary since the IRS gets the whole 1099-B.
I am hoping that starting the whole return over from scratch does the trick.
