I am planning to mail in my Iowa state tax return? The TurboTax instructions said to "attach copies of W-2s and 1099s to the front of the return".
For 1099s, does it mean all the different 1099 forms such as 1099-INT, 1099-DIV, 1099-G, 1099-R, ....?
Do I need to staple them to the first page of the Iowa return or just put them on the top?
Appreciate your help.
