I was surprised that TT didn't provide a spot to view this value.. Paraphrased the following from the IRS instructions for Form 8962:
Worksheet 1-1. Taxpayer's Modified AGI—Line 2a
1. Start with your adjusted gross income (AGI)* from Form 1040 or 1040-SR, line 8b, and Form 1040-NR, line 35
2. Add any tax-exempt interest from Form 1040 or 1040-SR, line 2a, or Form 1040-NR, line 9
3. Add any amounts from Form 2555, lines 45 and 50
4. Form 1040 or 1040-SR filers: If line 5a is more than line 5b, subtract line 5b from line 5a and add the result 5. Total is MAGI
