my activation code purchased from costco a year ago doesn't work its good for 8 returns (I used 2 last year for me and my husband - so should be 6 return left

You do not need to activate the code again if you have already done so with an account. To activate the code, simply use the same login credentials as you did the previous year and log in using the correct link for Tax Year 2023.

Thank you for choosing TurboTax.

Same here. I purchased a program to do 8, completed 5 in April and when I tried to do 2 more yesterday it is asking me for payment, despite clearly showing only 5 have been used.  Turbotax is suggesting I deleted some returns in order to free up licences?  I have been using this program for 7 years, doing primarily the exact returns each year. I have never had an issue until this year and support is unwilling to figure out the issues. Prefers to make false accusations. Horrible customer service.
