re/'Box 14 is informational only and does not need to be entered, usually.". I see many times a statement to that affect is said.
But isn't it true that depending what specific category you use from the pulldown, your taxes (either for Fed or State) ARE affected? In other words, sometimes it indicates a deductible mandatory state tax that isn't taxable on your federal, but other categories might be?? (like the medical cited in the reply?)
Help me understand why people say this?
