Not true. The refund-o-meter will need to start at how it looked when we had filed our return and then get adjusted as you make changes (amend). In my case my tax return was completed and filed. Also I had nothing flagged. I actually find the desktop version (amending) extremely useful as it let's taxpayers go back and modify things to see how next year's income can affect taxes owed. Sure it would not be 100% accurate numbers since tax rate/laws may be slightly different but it is a perfect tool for getting a good estimate. It can also let one see whether selling a property or taking a new job/salary really makes financial sense.
Every year I have used the amend/desktop software after completing and filing my taxes using the online TurboTax and never have I seen this issue. For 2019 they'd had issues with their programing. I say that because up until a month ago the .tax2019 file was actually corrupt!!!
