Line 23200 "Other deductions" -- How is this amount calculated? CRA asks me to submit the supporting docs but I cannot figure out where this amount came from.

[user13864129]

My Line 23200 shows the same amount as in 68080 "Any other investment expenses claimed in 2021 to earn property income", as well as "Foreign tax deduction under subsection 20(12)". I think I made some erroneous entries for some foreign investment tax slips. Could anyone help me which tax slips have tax deductibles, such as foreign tax withheld outside Canada?
