there are different MAGIs... have you checked Form 8960 instructions for Line 13
https://www.irs.gov/pub/irs-pdf/i8960.pdf
If you didn’t exclude any amounts from your gross income
under section 911 and you don’t own an interest in a CFC
or PFIC, your MAGI is your AGI as reported on Form 1040
or 1040-SR.
