Should I e-file after just mailing in past years?

[E_Ray]

I was way behind in my taxes (I did not owe any federal) but I finally got caught up and completed my 2019, 2020, and 2021 taxes.  It was too late to e-file those, so I mailed them last week, all in one package.  I'm working to get my 2022 done by the actual due date too, and I would be able to e-file.  But would that send up red flags or something with the IRS, with the previous years not having been processed yet?  Based on experience over the past several years, it's going to take them 9 months or so to get to the ones I just sent...

You can efile even though you mailed your others.
