I'm using TurboTax premier desktop version for Mac. This issue struck me too. Yuck! I've been TT user for years. This is probably the worst experience thus far. The desktop version was slow and somewhat buggy. Regarding this issue, I was able to go into the forms, top left, click Forms, then top middle, click Errors. The red arrow buttons appeared at bottom of screen. Clicking the red arrows took me to each field that had the error amount. For me is was 0. I put my mouse on the field. Then go to Edit menu. Under Edit, there is Override. Click that. Then you should be able to manipulate the field and put in the correct figure. Hit return and then you may see some arrows at bottom of screen to take you to next error. Repeat steps. Keep in mind if you enter .49 or less, the program is probably going to round you to 0. What a pain this is. Hope TurboTax and Betterment can get together on this. Good luck.
