Estimated tax return or will I owe?

I'm just looking to find out if I will possibly get a tax return or if I will owe money… I have not filed the last 2 years because I have been out of work the entire time cause I have been dealing with some health issues but back in September I donated my car to the Make-A-Wish foundation after it died, so I'm pretty sure I'mr required to file and I don't mind. The value on the car ('95 Honda Accord EX) at the time was approx $430… I just want to prepare myself in case I end up owing money… What are my odds of getting a refund or owing money? Any ideas? Thanks!
