Am I entitled to all of the commissions on shipments for orders I booked that go out after February 19?

I put in my two week notice on February 3, 2016. It stated that my last day would be February 19. I received a call from HR and my sales manager the very next day telling me that they will pay me thru the 19, but to turn in my company computer, phone, etc. and not to contact any customers. The company is based out of state, so I have a home office. If I booked something in January, but it doesn't ship until April, do I get commission? If an order comes in between the time I put in my two weeks and the 19th of February, am I entitled to the commission? I'm concerned with the new HR and CEO not wanted to pay.
