Can I count simulator hours towards a commercial flight certificate training?
According to the FAA, yes you can count those hours, but they can only count for only

Under FAR part 141:
7 hours(35%) of 35 hours of flight training towards a private pilot certificate
17 hours(50%) of 35 hours of flight training towards an instrument rating
36 hours(30%) of 120 hours of flight training towards a commercial pilot certificate
10.5 hours(30%) of 25 hours of flight training towards a multi-engine rating
12.5 hours(50%) of 25 hours of flight training towards an ATP cerfificate
2.5 hours(10%) of 25 hours of flight training towards a flight instructor certificate
1.5 hours(10%) of 15 hours of flight training towards an instrument flight instructor rating.

From what I see, you can probably fill up your remaining hours with sim time because you only have a little over 20 hours left and you can have 28 more hours of sim time towards your certification.
