I need to update turbotax from 2019 to 2020. I followed the instructions and it did not appear to work. My return was asking 2019 questions

Each tax year has its own software.  You cannot update a 2019 CD to prepare a 2020 tax return.   You need to purchase 2020 software.

2020 TURBOTAX

You can also purchase the CD/download from various retailers such as Costco, Amazon, Walmart, Best Buy, Staples, Sam’s Club, etc. etc. etc.

This link Where can I obtain authentic TurboTax software? has a list of authorized TurboTax resellers.

When you use desktop software, there is an additional fee to e-file a state return.  You can avoid that fee if you print, sign and mail the state return.  The state e-file fee is $19.99 and increases in March.
