It still shows error

@nk420074 Are you using a TurboTax Online Version or a TurboTax Desktop version? What error are you getting? 

Turbo tax online, but when code is used it says invalid. It is Turbo tax basic with 4 returns and download only.

@nk420074 to use the Desktop/ Download version please use this link to download TurboTax Basics use the license that you already have. This is not a Online version. 

I tried this and the assistant tries to help but EVERYTHING we tried did not work! I paid 40 dollars and it is not working! she said it happened before and I have to contact the store but I do not have the receipt I bought this at the beginning of last month Never had problems with Turbo tax before...but I won't trust this again with a new one!

Tried everything it is the online  version and NOTHING worked even with phone support
