Can you still efile 2019 return if 2018 federal was mailed 3/20 and not accepted yet

I am trying to efile my  2019 federal return prepared using TT.  My 2018 federal return was prepared through TT and mailed in March 2020 which the IRS has not approved yet.  My 2019 return was rejected because IRS is saying AGI is wrong.  Would I still be able to efile my 2019 federal and state? 

Thanks, 

SR
