As tax guru @Critter-3 said, it sounds like you are confusing taxable income and tax liability.
Taxable income is the amount AFTER deductions. So if you have $60,000 of income after subtracting your mortgage interest, property taxes and charitable contributions, then you will pay federal tax on $60,000.
If $60,000 is your income, then:
$60,000 – ($18,000 mortgage interest - $7,000 property taxes - $11,000 charitable contributions) = $24,000 in taxable income. The federal tax on that amount is about $2,675.
You can’t deduct federal taxes paid on either your federal or Maryland return.
If the $16,000 of IRS taxes assessed for 2022 means the amount of federal tax withheld from your pension, then you will get the difference back as a refund ($16,000 - $2,675 = $13,325).
