How do I add my Robinhood securities/crypto forms if I already filed my taxes?

[SForrestLO]

You can't make changes if you filed your taxes. Depending on the circumstance you may be able to amend your return.

Please see this Turbo Tax FAQ on when to amend. When should you amend your return

To amend your return, wait to see if your return has been accepted or rejected by the IRS or state. If rejected, you can correct and re-send your return. If accepted you should wait until your return has been processed and you receive your refund or confirmation that any tax due has been paid. If you file an amended return while your first return is being processed it can cause extended delays for both returns if two returns are in the system at the same time. In addition, if the IRS makes any change on your original return, you might end up having to amend the amendment. Amended returns can only be mailed - allow 8-12 weeks - can take up to 16 weeks (4 months) for processing.

This Turbo Tax FAQ will show you how to amend your return. How to amend (change or correct) a return you already filed.

do I need to amend state return for this or just federal return?

If you filed a state return, it will also need to be amended. Do not amend until original payments are all processed. Please:

• Save a copy of the original return before doing an amended return.
• See how to file an amended return.
• Follow your amend at track an amended return 
• Here is a great FAQ to show the math for amended returns. 
• If you will owe money - make that payment by April 18 to avoid penalty or interest.

In addition, you may need to file a state return. If you must paper file, tracking is recommended.
