I received a 2016 1099MISC for $752.40 after I filed for 2016 does this meant that I have to file an amended return which includes this income?

Unless you did include this income in your original filing you will need to file an amendment.  The IRS will reconcile the 1099MISC income they show as being reported to you and what you have reported as income on your return.

If you can file the amendment by 4/18/17 there should be no penalty but if you wait and owe taxes on the additional income there may be late payment penalties added to your additional tax.
