Since you are using the
TurboTax Home & Business version and not the online version, your tax data is stored locally on your computer and TurboTax will not have the data information stored in that file. The .tax file stores all of the data needed to transfer the information into the program. You might check to see if you have a .tax file for 2017 backed up externally before you did the clean install. Unfortunately, the PDF file is limited as it is a non-editable "snapshot" of your tax return that can be opened, viewed, and printed in a PDF viewer program, but not edited or amended.
TurboTax Home & Business
charges you to e-file the state, but does not charge to prepare the form as one prepared state form is included with the Home and Business software (giving you the option to print/mail and not pay to e-file). It might be asking you to purchase again because the state was technically "used" the first time and the program thinks you are adding another state (which does cost extra). I can't say for certain that is the issue; that is just my best guess.
Since you have not received anything in 2 weeks, you will need to contact a rep. for assistance with the state. As far as proving you paid, if you e-filed, they should be able to locate the charge. The only way they would not see a charge is if you purchased the software from a retailer and print/mailed the free prepared state form.
They are not open on the weekends off-season, but are open Mon - Fri 5 AM - 5 PM Pacific.
P.S. If you purchased anything to download from TurboTax, you can access your downloads with the link provided. You mentioned that you might have multiple accounts, so you will want to check both e-mail accounts by logging out of one and into the other to check.
