Thanks a lot for your quick response. I also looked at the form schedule a 'Medical expense worksheet' and found that amount paid through HSA was being deducted from the amount paid through my credit card, which is not correct because overall amount I paid was = HSA+credit card. So, to make it correct, I have to add HSA amount as well so that correct equation could be = (HSA+credit card) - HSA. Thanks again!
