Carmen feels very charitable in 2020, and makes the following payments:

                $5000 to Harvard University
                $10,000 to her local food bank, a qualified charity
                45 hours of her time to the food bank (Carmen earns $32 per hour)
                $450 in expenses while volunteering at the food bank
                $1000 to her friend running for mayor
                IBM stock to a qualified charity; held for 5 years, FMV = $10,000, basis = $20,000
                Exxon stock to a qualified charity; held for 3 years, FMV = $40,000, basis = $15,000

Carmen has 2020 AGI of $75,000. What is her 2020 charitable contribution deduction and carryover, if any?
