I received the following message but it is not true-all the W-2's have amts: One of the W-2s doesn't have an amount in box 1 or amount is less than $1.

You may have a W-2 that transferred from the prior year that you didn't delete or didn't use for this year.  

Go back to the Federal Taxes tab and update the W-2 section.  Delete whichever W-2 shows no wages for Box 1.
