How do I report that I retired in 12/2016 and received pension and one last paycheck in2017?

I receive monthly pension checks and I have the taxes deducted.

This is not uncommon. You should have a 2017 Form W-2 from your former employer.  Enter it as wages in the same way you did while you were still working.

And pension payments you received in 2017 should be reported to you on Form 1099-R.  Enter it as retirement income in TurboTax
