When I filed my taxes in April I paid exactly the tax TT said I owed. Now I got an IRS notice CP23 saying I underpaid by a couple of hundred bucks.
Puzzled, I opened the pdf copy of my return saved in April and verified that I had paid exactly what TT told me to then.
Next I opened the TT desktop app -- it went through a series of updates that it usually does -- and went to Personal >> Federal Review >> "Federal Taxes you owe". The amount TT shows there now is higher, and in line with the IRS notice!
What gives? Why the discrepancy between the pdf I saved in April when filing my taxes, and what TT shows now in June? I haven't opened the app again in the past two months, and haven't entered any new data. Did the software updates TT keeps doing force any adjustments?
