For the Turbo Tax fees or for tax due? Your only proof of payment is your bank or credit card statement showing it coming out. Turbo Tax does not pay it. They only send your bank info to the IRS or state for them to pull it out of your account.
Is it for state tax due?
Check the printout or PDF of your return; look for the state cover sheet with the Turbotax logo. If you owed tax, it will show the payment information and how/when you decided to pay. Read the state payment instructions carefully since most states cannot be paid from within the TT system and requires additional steps.
