Why does my completed Federal return have zeros for everything? No income information??? Did i forget something? It checked everything and said your ready to print... Any help?
It depends.
Make sure you are logged in using the same credentials you used to enter your tax return information in for 2019.
Please see the following link to verify any accounts under your log in credentials to ensure you are using the correct account.
Account recovery if unsure of user ID
Also be sure you have not already electronically filed your return. Please see the following link for instructions to confirm the status of your return. If you have already electronically filed your return, the tax return will be shown as not having any information and could be the reason you are seeing $0.
