I am currently pay back taxes owed for 2011-I pay a set amount every month to the IRS-and I have not filed taxes since then as I was only receiving social security and

Yes, I only filed once in 2012 after the 2011 taxes-it was to get a 1000 dollars, thru H&R Block, but it went directly to the IRS-I knew that' was accurate-so should I continue to file, and will if I get a refund go to the IRS?
