ACL use either hosts or networks, not ranges.
Networks are bounded by power of 2 values. Your range doesn't correspond to a single network.
The best you can do is split your range into 4 valid networks:
192.168.1.10/31
for IP 10 & 11
192.168.1.12/30
for IP 12 to 15
192.168.1.16/30
for IP 16 to 19
192.168.1.20/32
for IP 20
So you don't have to use 10 lines but 4 is the minimum.
Alternatively you should organize your hosts differently so your ACL match a network.
192.168.1.0/28
match IP 1 to 15 (well 0 to 15 actually, but assuming you use 192.168.1.0/24, 0 is the network address and cannot be assigned to an host).
192.168.1.16/28
match IP 16 to 31.
