USA $1 - Error on line or new line needed??

1 Dollar (Federal Reserve Note) - United States – Numista

I have 2021 $1 F Atlanta, GA note made in DC not Fort Worth. Is this an error on the line or does a new line need to be made?

Serial number is F########F. 

From what I know, newer issues of US $1 bills are typically added to the Numista page as they are found in circulation. You should be able to add it as a year line on that page so long as you provide proof that this note is indeed what you describe it to be.
