So, after digging and digging, I noticed my forms in TurboTax for my w2's didn't accurately match one of my w2's.
One of the w2's had the same amount in box 10 as it did in box 1.
As I didn't have the accounts that justify dependant care benefits being populated in my w2 (nor was the box populated in my actual w2) I simply deleted the value of box 10 (there were two of them in the w2) and it had no impact to refund amt etc, however after going over it a dozen times I finally just clicked efile.... And my w2's in tt perfectly matched in form and actual paper.
40 min later I got the happy dance response of "Your federal tax return was accepted by the IRS"
Good luck everyone, I guess TurboTax "checking for errors" misses this actually obvious flaw.
Of note, even if I manually add the w2, and there's no field for box 10 in the input... It's populated in the form.
I believe it's a tt bug.... But good luck everyone!
