:confused: I filed an amended return for 2005 & 2006 for both Federal and State. I mailed off everything in early March and immediately received my 2005 State return. I have not received the 2006 State or Federal for both years. Are you aware of a website that I can research for returns for prior years?

To process amended tax return, the IRS takes 8 weeks to 12 weeks. Also you can not check the status of your amended tax return on line.
You can call IRS after 8 weeks. Before you call, you must keep some information handy: read: Your U.S. Tax Return: When will I get my tax refund?
