IRS site says 2018 taxes not filed, but i did it through Turbo Tax

I am having issues getting my 2019 returns rejected.  I am taking my AGI off of last years return, but went to IRS site as instructed through help section on Turbo Tax site.  There doesn't seem to be a record of me filing taxes last year.  

I need help a) confirming my taxes were filed by Turbo Tax and b) getting my returns in properly.

 

Thanks, Kelly
