I am sorry but this has happened in 2020 as well and has been reported by me as well. 2021 once you go over roughly 10 w2g forms the whole software just lags and gets worse. This should of been fixed for 2021, Unfortunately, I tried filing it online last year and the online version worked but I didn't submit due to my wife's health and passing. Now I am scrambling how to complete 2020 taxes. Can't do it online
