2022 Amended return amount owe

Hello, I filed original return in early March now I amend the original return . My question is, the $ amount difference in amended return is say $ 800, turbo tax is asking to send a check for $ 800 with the amended return. Will IRS refund the original return amount which means that IRS did not deduct any amount so therefore when I file amended return I pay back IRS $ 800 OR do I just file amended return without a check for $ 800 and assume, that based on the amended return IRS will only issue refund of the amended return.  Please help me.

Thanks, Casey007
