After you file

I submitted my info for 2019 as 2020 without realizing it. I already emailed my federal tax return as 2020 when it should've been for 2019. State return not ready for file because it's waiting for additional form to be submitted.

In this situation what am I suppose to do?   Sit and wait until they reject or accept? after that what do i do with state return ? do i file it or not, if yes then my taxes for 2019 and 2020 will be in 1 form and filed as tax return for 2020

Please help me resolve this issue
