2018 filing return info

After filing my 2018 return I chose not to print a hard copy as the record was on my computer.  Unfortunately, my computer since then has failed and needed to reinstall windows - that record is gone.  Why is TurboTax telling me it will take 6 weeks for them to report the information in that return to me?  I also trusted in the pin from 2018 as a filing key for 2019.  Turbotax or the IRS won't accept that pin number.  Thus I am required to enter an income figure that I have no record of and must wait 6 weeks to have Turbotax provide that information.  What is up with that????
