I claimed my missing $600 stimulus on my 2020 taxes and e-filed last week. Today the IRS website shows they'll be mailing me a check on February 2.

I claimed my missing $600 stimulus on my 2020 taxes and e-filed last week. Today the IRS website shows they'll be mailing me a check on February 2. Will this cause problems with my 2020 return since I've already e-filed and claimed the $600? Does this mean I'll be audited?
