What will be the AGI if we have filed an amendment? Will it be the amended return AGI?

No.  You use the AGI from the original 2018 return.

You need your 2018 AGI to efile 2019. The AGI is on 2018 1040 line 7. If you filed a Joint return you use the same AGI for each spouse.

When did you file 2018? If it was late in the year try putting in zero for the AGI. And see, https://ttlc.intuit.com/community/rejections/help/what-if-i-entered-the-correct-agi-and-i-m-still-ge...

If your spouse died during 2019 there is a problem efiling and you will have to mail your return

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.

We used turbo tax last year we filed jointly. Our returns filed this year were rejected and we are being asked for 2 agi numbers. The one number for myself accepted, the one for my spouse was rejected.

@David swesey  If you filed a joint return for 2021 the AGI is the same for each of you.  It is the amount on line 11 of your 2021 tax return.
