Can I use Turbotax online to complete 2004 Federal and State returns?

[Critter]

No ... Turbotax only supports tax years 2015 thru 2018.   If you need to complete a return that old you need to get the forms from the fed & state websites and complete them manually   OR  seek local professional assistance.

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.
