If you have entered taxable pension income, this screen will state the following:
"You have taxable pension income on Line 5b of Form 40 Part I. If any of this amount was received from a retirement system listed in the instructions for Part I Line 5, the amount is NOT taxable and should not be reported. If this is the case, enter a zero on the taxable pensions line."
The screen also lists some examples of exempt retirement systems. Change the taxable amount for Alabama to zero if it is not taxable.
