Refund amount changed after software update
Back in April I filed an extension on my taxes waiting for a final form to be ready. I filed the extension on April 14th so all tax forms should have long since been finalized. I finally received my last form today (mid July) and opened TurboTax on my PC. As always it downloaded updates but didn’t tell me what the software update changed. After this update, but without me changing anything, my refund amount is now $1,500 less than it was when I filed for the extension. I don’t have a PDF of the old version because I didn’t file at that time and I only save/print a PDF of my completed return.
How can I figure out what was changed? There is no way the tax calculations could have been updated in the time since I filed for the extension because I filed when Federal taxes were already due. How can I find what the software updates actually did, the history just say “Program Updates released 7/9/2026.”
