Here's how to pay for your PLUS upgrade in your already-filed 2018 return (I assume, depending on what you mean by "already did 2018 taxes".) It's a different method than the steps you were using.
Since you said you have already upgraded to PLUS, I won't include the upgrade steps, but will go directly to the payment steps. As I mentioned above, this will only work if the 2018 and previous returns are in the SAME account.
If you have already filed your 2018 return, you may already know how to open your 2018 return back up, but I've included that here, too.
- Log in and go to the section "Your Tax Returns & Documents".
- Expand that section and choose 2018.
- Then click the link "Add a State". (you aren't really adding one; that just opens the return back up.)
- Since you said you have already upgraded to PLUS, then you just need to pay. Do NOT upgrade any farther, or you'll have problems.
- In the left menu column, click on TAX TOOLS, then choose PRINT CENTER.
- In the Print Center choose "Print, save, view THIS YEAR's return." (yes, you say "this year's" because you are paying for PLUS 2018 to unlock the prior returns.) You don't really have to print it.
- On the next screen choose to PAY NOW. (for this unlocking purpose, you cannot use the "Pay Later" feature if it's offered.)
- The next screen will be an Order Summary. It should show PLUS for 19.99.
- Next screen says "Pay with Credit Card", but it can also be a debit card or prepaid debit card.
NOTE: Do NOT use this method to open a return to make changes/edits to an
already-filed return (one that has actually been mailed or efiled.)
If you later need to make changes to an already-filed return, you have to
go through the formal amending process, and your return must start off
exactly as originally filed.
NOTE: Remember all PDF tax documents and data
files are very sensitive files, since they contain your personal ID
info, financial data, and possibly bank account numbers, etc. Be sure
to store them safely and securely to guard against computer theft,
hacking, etc.
