I found what I believe is a calculation error on Form 8829. When the online TurboTax SE system multiplies line 41 (2.5641%) x line 40 ($75,914) it gets $1,975. But that is not correct. It should be $1947 just as it was on my form last year because lines 37-40 have not changed. Consequently, the system wants to depreciate my home (for home office deduction purposes) an extra $28 this year. I even checked the worksheet and it is using the same incorrect number there as well. I called TurboTax Live to report this but was only able to speak to a tax expert, not the IT department. The tax expert said there is no way to edit this number directly on the online version. I was told I would have to download the software and redo my entire return manually. I don't have time for that, sorry. Isn't there someone in IT who can fix this issue, which appears to have also been reported in 2021? Why is this technical problem still unfixed? Can someone help me fix this on my return online so that I don't have to redo everything using software I have to download to my computer? I have already paid for my online Live version. Thank you.
