@fredchikin You got it right and thanks for looking into it. I am claiming standard deduction. Therefore as per IRS instructions for form 8829, both the real estate taxes and the mortgage interest payments will go in the excess mortgage payment and excess real estate payments.
I will not correct my entries in form 8829. The below is from the IRS instructions
"Taxpayers claiming the standard deduction. If you claim the
standard deduction, you will not include any mortgage interest or
real estate taxes on lines 10 and 11; instead, you will claim the
entire business use of the home portion of those expenses using
lines 16 and 17. "
