Turbo tax is forcing me to upgrade to premium which I don't need

[yohann13]

Read the message carefully.  
You should not require Premium.  It usually gives you this message when you are entering an IRA amount or other stock/mutual fund questions.

TT premium or  Quicken Premium are only helpful if you do your own stock planning, sales, and purchases.  They can help you minimize stock gains and/or find lossses.

You can skip the upgrade if you have a very vanilla tax return.
