Sorry, I should have described more.
These lights are in 4 separate areas/rooms of the basement, on 4 separate switches. Approx 6 lights per room/switch.

Feed a central junction box with a 20 amp circuit using #12. You can tie the 4 separate #14 circuits together in that junction box. Remember to put the junction box where it's accessible. ^_^

I don't think this is allowed or even a good idea. I'd go with 2 15 amp
circuits to provide some light if one breaker trips (someone suggested).

Actually it would violate code to tie #14 TO #12 on a 20 AMP circuit. The OP wrote that he's using LED bulbs that operate on 9 watts each. The 13 LED bulbs will draw about one amp all together. I'm quite sure a single 15 amp circuit will handle that. ^_^
