most of retirements are exempt from KY tax. How do I enter into KY P form to show that on turbo tax deluxe?

Turbo Tax will automatically subtract the income and create the Schedule P if needed.  Did you receive taxable pension or retirement income
greater than $31,110?

All pension and retirement income paid under a written retirement plan is eligible for exclusion. This includes pensions, annuities, IRA accounts, 401(k) and similar deferred compensation plans, death benefits, and other similar accounts or plans.
