I filed my taxes early this year. Then I realized I forgot a W-2. TurboTax told me they weren't ready to process amendments yet, but I was impatient. I found a way to fill out an amendment form, so I did. Only after I mailed it in did I realize the form was in fact for tax year 2014, not 2015. The data on the form is all correct for 2015, but it has the wrong year at the top (part of the form, not something I entered).
I made this mistake with both my federal and state return.
Before I call the federal & state tax agencies to try and sort this out, is there a standard procedure I should follow?
I noticed there's a very similar question here: How to amend an amended return? but in that case, the error was not with the form itself. When I check my amended return status on irs.gov, it tells me they have received and are processing an amended return for tax year 2014 (only). This makes me think if I file one for 2015, it will not affect the one for 2014, so I'm hoping for a different answer that addresses that specific concern.
