Deductions & credits

I have already read all of this -- my issue is in translating what is being said into actionable items.

 

I understand I can claim the entire per diem amount, but I am still unclear as to WHERE I claim it.  Example:
I am going to claim $10,000 is M&IE for 2021.


If I file this under Travel Expenses or Meals 100% in Turbotax, my refund is adjusted by MORE than if I file this under Meals 50%.

 

The only thing I am unclear about is which category I am allowed to claim the $10k for M&IE as this has a monetary impact on my return.
