Hi, I am not supposed to get any refund this year. And my tax file showed "accepted" on TurboTax. Does this mean everything is done with my tax this year?3

Yes, that is correct, you just need to save the appropriate files for your records.

it is extremely unusual for a taxpayer to end up in a break-even situation. you neither owe nor are due a refund. it is possible. to be sure check the return page 2 lines 34 and 37
