You got me curious…
Your total above 10786 + 10980 + 4350 + 3705 + 10106 + 9852 + 7804 + 1164 + 224 = 58,972 including the tarped off capacity.
per fightingillini.com there are 42 600 and 700 level suites with each having an entitlement of 18 tickets. That’s 756 total.
58,972 plus the 756 is 59,728.
This map indicates 800 level suites as well, but I didn’t see reference to them anywhere for sale so assuming there isn’t demand and they’re currently not in use.

ADA also requires 36 handicap seats plus 1 additional for every 200 seats over 500 = 36 + (60,670 - 5000) / 200 = 314 (potententially lower by a couple seats depending on if the math includes or excludes ADA seats)
221 Assembly Areas - ADA Compliance 221 Assembly Areas Wheelchair Spaces/Companion Seats. Owners of large assembly areas have historically complained to the Department that the requirement for one percent (1%) of seating to be wheelchair seating is excess

The suites and ADA brings the total to 60,042.
The 3D render linked from fightingillini.com shows 4 rows of band seats, and Wiki claims membership at 400 but 300 surrogate cardboard cutouts were used during COVID in place of band members.

Band brings total to 60,342 - 60,442.
Seatgeek shows 3 800 level suites that occupy similar space to 8 lower level suites. Presuming similar capacity that 8*18 = 144.
New total 60,486 - 60,586.
That still leaves 14 to 114, and now I’m going to lose sleep over it too. Lol.
