After you file

Always print a copy of your completed tax return for your records, and review it carefully before e-Filing.
You will need it if you are audited by the IRS, or to amend if a TurboTax update changes your return or for any other reason.
AND, to find your AGI next year.

Put the paper copy aside for three days. Then review it again.

If there is an error you'll probably find it.

 

ALSO, examine 1040 Line 5b.

If there is an amount there, that's a difference since that amount is taxable.

Double check that all your W-2 numbers are correct.
