I would like to file my taxes for 2020. I am a full time college student and listed as a dependent on my fathers taxes. What package would i purchase to file?

Did you have income?  

Sorry it's too,late to start a 2020 online return or use the mobile app, either on Turbo Tax or the IRS.

To do a prior year return you have to buy the Desktop program here.  Deluxe should be enough.  All the Desktop programs have the same forms. You just get more help and guidance in the higher versions.

You will need a full Windows or Mac to install it on.

If you have a simple return and want to file for free you can fill out the forms by hand.  Here are some basic forms.....

Here is the 2020 1040 return

Don’t forget your state.  And you will have to print and mail your returns.  So be sure to attach copies of your W2s and any 1099s that have withholding on them.  You have to mail federal and state in separate envelopes because they go to different places.  Get a tracking number from the post office when you mail them for proof of filing.
