Federal Amount due on 1040-SR different than amount shown on filing instructions

The amount due on tax year 2025 1040-SR line 37 "The amount you owe" is shown to be $796.  Also the "Federal Tax Due" window in Turbotax shows $796.

 

But on the page, "Electronic Filing Instructions for your 2025 Federal Tax Return":  

"Your federal tax return (Form 1040-SR) shows a balance due of $793.00.

 

Your return shows you have elected to pay your balance due of $793.00
by Direct Debit using the following information:
Amount Withdrawn: $793.00"

 

I've efiled and scheduled a payment to be made for $793 in April of 2026.  So now my scheduled payment is $3 short.  I haven't found a way to modify the scheduled payment amount.

 

Why and how could the two amounts be different?  I've rebooted and restarted several times, but the amounts remain to be different.

 

Thanks!
