@heavy208 Just did some more testing on an online TurboTax edition.
When just entering an amount for 2020 Form 8915-E, Line 9 only, that amount did Not flow to the Form 1040 Line 5b
However, by also entering the same amount for 2020 Form 8915E, line 9, if you checked the box on that line, enter 0, then the amount did flow to the Form 1040 Line 5b.
Try this and see if your tax refund decreases or the taxes owed increases
