<prompt> Human: For example, I usually use TurboTax, but I have an HSA now so they want to charge me to file. I found out CreditKarma has free filing year, and I also found out they had a lot of issues last year. Instead of blindly trusting something Ive never used just to save some money, and instead of accepting my fate with TurboTax, I filled out my information on both CK TurboTax and made sure they matched up. Then I just submitted with Credit Karma for free.This is probably common knowledge to a lot of people, but I saw a lot of people saying various websites messed up their return and they never used them again, when they could have easily verified that amount with a different tool.  <response>: Did this last year because I didnt trust any program in its first year. Numbers were an exact match so I went ahead after looking over the forms. Seemed to do OK. Good advice, OP.
