Help: Form 1040 line 37 "amount you owe" is coming up as blank -- is this accepted as a 0 by the IRS?

Hello.  I paid the tax owed plus the estimated penalty when I filed for the 2024 extension -- resulting in "amount overpaid" (line 34) equal to "estimated tax penalty" (line 38).  Line35a is 0 because I'm not asking for a refund.   

 

"amount you owe" line 37 is coming up as blank but I was expecting a 0.  Is the blank on line 37 accepted as a 0 by the IRS?  I would like to e-file.
