Check
The correct sentence will be "I have to hand in my paper to Dr. Soriano by late morning on Tuesday".
It should be noted that the use of a.m and p.m is more applicable to a number attached. For example, this is better used in cases such as 7a.m, 2a.m etc.
On the other hand, in this case, a number isn't attached. Therefore, I have to hand in my paper to Dr. Soriano by late morning on Tuesday" is better.
