<<Just file in 2021 for year 2020?>> YES!!!
<<And getting taxes done earlier than later will have no bearing on when i might recieve any owed stimulus? >> CORRECT.
Infact all PAYMENTS will be stopped by the IRS on January 15th (by law) so there is no confusion whether you should be waiting on the payment or just filing for it through the 2020 tax return. The tax return window opens in late January so it looks like the IRS is giving it two weeks to let 'checks in the mail' flush out.
My only caveat is that you don't want to do it too early and find out that the turbo tax software wasn't updated to accommodate the 2nd stimulus. They have until the end of January to update the software and the IRS just released the requirements on Wednesday, so hopefully it'll be done by Jan 27.
<<What is your guess as to when i could possibly receive stimulus #2 if owed,using tax return??
it's just going to be part of your refund as part of your 2020 tax return. If you file and request Direct Deposit, it normally is refunded to you within a few weeks, but if you get a child tax credit or Earned income credit, the IRS can't release the refund until mid-Feb

for the prior AGI, use zero, see if that works
does that help?
