My experience: both tax year 2019 and 2021 after my return was accepted by the IRS, I later opened these 2 tax returns. In both cases the tax amount calculated by TT differed from that on my accepted return. In both cases TT updated the program when I opened both of these returns. In both cases this was done after the April due date. It appears that the updates caused this to happen. This tells me that to get an accurate tax calculation I had better file a 6 month extension for my returns in the future. Is TT that buggy? The answer is YES!
