On a Joint return there is only one AGI.  It is not broken out.  You would have to add up each person's income from their W2 and 1099.  Why do you need to know?  Are you trying to enter the 2019 AGI to efile?  You use the same AGI for each of you.

When filing as Married Filing Jointly all amounts on the tax return are the combined income and expenses for both of you.  They cannot be broken out by individual.

You can look at the individual worksheets for separate income in the PDF download.

I just need the dollar amount for 2020

When you file married filing joint, there is no personal AGI, it is the AGI that you want.  Your AGI can be found on Line 11 of your 2020 Form 1040.   

If you do not have a copy of your 2020 Form 1040 and you filed your 2020 Form 1040 with TurboTax, use these instructions on how to get back to a copy of your 2020 return:

I have the same problem. Rejected for IND-032-04 - 'SpousePriorYearPIN' or 'SpousePriorYearAGIAmt' in the e-mail from IRS. TurboTax says incorrect value of spouse's AGI. We filed jointly both this year and last year. I can find nothing on any form labeled 'SpousePriorYearAGIAmt' from eithe 2021 or 2020 returns. My free return transcript for 2020 also has no space for that AGI. The joint AGIs on both years forms match exactly. 

What's going on?

Try using zero.

Try using zero where? There are no fields for spouse’s AGI. 

Go back through the File tab.  It should ask for both your AGI if you are filing Joint.  I bet it needs 0 for your AGI too.

I haven’t checked that yet, but the TurboTax panel that comes up to describe the problem. It has a field for the spouse’s AGI. If I change that entry to zero and resubmit, my return is accepted.
