Once I entered the rounded amount of Form W-2 Box 11 into the second field, TurboTax automatically updated the the State Allocation amount to the same amount and showed no error. In fact, I can put any whole dollar amount in the second field and TurboTax will match that amount in the third field of Box 11 with no error. It seems that should be incorrect. If I add any amount in those two boxes with cents included, I get an error.
