Same issue. CD Deluxe version for MAC. Annoying, esp. when TT indicates return is error free yet still receive this annoying error message. F1040X-007-01 - Form 1040-X, 'TotalNonrefundableCreditsAmt' in 'CorrectNumberOrAmountGrp' must be equal to the amended Form 1040, 'TotalCreditsAmt'.
One field on line 7 of 1040-X is "0" and the corresponding field it should match on line 21 of 1040 is "blank", and when you try to edit the field to make it "0" no can do.
I'll try Intuit support but judging from other comments it appears they are aware of problem and working on a fix. One note said it was "solved" but my submission attempt was rejected yesterday, so we'll see.
