Hi. I filed my federal returns electronically. IRS sent me notice that they automatically corrected my return, no amended filing needed. I had printed my CA taxes but not yet filed by the time i got this letter. When I discussed with Intuit they suggest I do amended federal return in order to generate an amended CA return. I actually did not file my CA return yet as the letter from IRS came before I filed. No rush with CA return as they owe me money. So now I have my CA amended return and FED amended return printed, even though I didn't actually file an amended federal return and did not file my original CA return. The instructions say to sign the returns. Do I need to sign the Federal Returns even though they were filed electronically. If so , both the original and amended? plus the CA amended?
