Does turbotax offer e-file?

IRS will take 4 months to process snail mail.

You can use TurboTax to e-file a 2019 tax return up through October 15, 2020

However ... if you have already mailed in a 2019 return then do NOT efile the return now ... doing so may delay things even further when 2 returns show up at the same time.
