I made three colums, all labeled "Box" to signify the three indistinguishable boxes. Writing out the combinations I found there could be


5 in one

4 in one and 1 in another

3 in one, 1 in another, and 1 in the last

3 in one and 3 in another

2 in one, 1 in another, and 2 in the last


for a total of five solutions.
