<prompt> Human: the free credit karma online tax prep software has a bug regarding HSA distributions on the 1099-SA form. The software does not have an option to declare that your distrubtion was used on qualified medical expenses. Therefore you are taxed an ADDITIONAL 20 on all HSA distributions from the 1099-SA. This issue has been found by other users and is still not fixed as of today;.  <response>: I filed with Credit Karma. Just checked my return and realized I have 0 under my Part 2 of my 8889 for my HSA, meaning I never had to fill out a 1099-SA. It should read about 450 in qualified medical expenses. I guess I would have to amend either way given the bug in OPs post. Can someone provide guidance on how I can amend my return?
