I need to find my ibi number or my earnings gross number when i filled in 2019

You mean the AGI?  You need your 2019 AGI to efile 2020. The AGI is on 2019 1040 line 8b. If you filed a Joint return you use the same AGI for each spouse.

How to find the AGI.

If you didn't file 2019 or filed it later in the year then try entering 0 for the AGI. If that doesn't work you will have to print and mail your return.

Or request a transcript from the IRS

 Do you mean AGI (Adjusted Gross Income)?
