If i self prepared my taxes on turbotax and printed my taxes out to mail in, do I sign where its says taxpayers signature/date as well as all spots that are listed for self/paid preparer's signature

No,  you do not sign as a paid tax preparer.  Your return prepared on TurboTax software is "Self-Prepared."

You just put your signature on the line that says Sign Here--and write in the date.  Your spouse needs to sign if it is a joint return.

I had to resubmit my taxes for 2020 because I didn't get my refund due to corona virus & I prepared it myself & had to mail it in & wasn't sure if I had to sign on the preparer line 

Thank u so much I was worried that I did something wrong thank u again God bless
