@mariagonzales Yes you can still efile from Online version or Desktop program. I don't understand what problem you are having. But you can only efile a current year 2021 return. I have a feeling you efiled your 2020 return now in January 2022. In that case it was efiled as your 2021 return not 2020. So it thinks you already filed 2021 and won't let you file your real 2021 return.
