Thinking about switching from Verizon to T-mobile with payoff promo. Need help

Hey everyone!

Trying to figure out ho to switch to T-mobile from verizon

I see Tmobile offers to pay off the rest of the phones payments

They say on the main page that you need to provide screenshot of the remaining payments amount...

but In the instructions it states that regular screenshot of summary wont work... and they will deny application for payoff if you'll send only summary

its confusing, because I dont have anything else... I have only summary where all details included... and there is only one option is to click on "payoff" button and there is a worming, that if ill continue there will be no option to cancel it and I will need to pay it off

What exactly do they need? Do I really need to continue and send a request to pay it off even before porting out my numbers?

Can anyone who switched over from Verizon, can share a screenshot of what you used (what info they really need)? Because even with an example from ATT, its not really clear where they get that additional info on screenshot on the right of a, similar to verizon, summary page

Also, will you have enough time to receive a payoff gift cards to pay for you final bill?

Thanks in advance!
