Forgot to put 1099 on tax return

I already filed my taxes for my husband and I this year and I forgot to add a 1099 form.. its just from a savings account that I opened with the place that I finance my car through. Its only got like 20 bucks in it and maybe earned a few cents interest.

I already filed my taxes though and they were already accepted... do I have to amment my taxes now? I paid the extra money to have a tax professional review them and it was accepted
