Where can I find a payment voucher to print and send in for a tax owed?

I have updated my original answer.  Perhaps this will help.

TurboTax assistance was very helpful, will use TurboTax again

You can get a copy of your federal & state tax return (and all of their accompanying forms, worksheets, payment vouchers, etc.) by following the directions below.  The state return should be at the bottom of the federal PDF file.  Scroll way down.  [Please note Step 8 below.]:

1. Sign in with the same login you used when you filed your return.
2. Click the down-arrow next to My TurboTax
3. Click on the My Tax Timeline
4. Scroll toward the bottom of that screen, in the Some things you can do section, click Add a state (This is just a workaround - you are not really going to add a state - program window will spin/update).
5. Click down-arrow next to My Account (top right, next to the Search box).
6. Click on Print Center.
7. Click on Print, save or preview this year's return.
8. Under Choose your option:, select Forms filed with the government (shortest version w/filing instructions); Forms filed with the government plus all worksheets (w/filing instructions); or All forms (longest version).
9. Click on View or print box.
10. Pop up will ask if you want to Save file or Open in Adobe.  (Filing instructions are on the first page.}
11. When finished, Click on Tax Timeline to go back to original login screen.
