I currently have a 1042-S that I received in 2012 as part of a scholarship. I did not file taxes in 2013 as I was new to the country, had no other income and was unsure of what to do - I am an international student on an F-1 visa, and obtained an SSN/EIN in 2013. At the time, I thought I had to file a regular form 1040, and hence i had trepidations about filing without an SSN/EIN.
I tried to file it in 2014 with a completed 1040NR-EZ for 2012-2013 and a completed 1040NR-EZ for the tax year 2013-2014, where the only item on the latter was the income from my 1042-S form. However, while I received a tax refund for the 2013-2014 year, no action seems to have been taken on my 2012-2013 tax return. They clearly received both as I sent both in the same envelope, but I am not sure what happened to my 2012-2013 filing.
I am unsure of how to proceed. The IRS does not appear to have any way to track late filings or filings from previous years, and I have already tried the only avenue I know of. I would appreciate any advice.
