Camshaft pulleys are at TDC but crankshaft is not.

The camshafts are at TDC but the crankshaft is not. I went to rotate in either direction but it stops at either the 2 or 10 o-clock position. Not letting me get to the 12. In either way I try to crank it. There is significant resistance and I can’t figure out why. I’m afraid if I keep trying to crank either way, I’m going to or already have damaged something. It’s like it’s hitting something and just won’t budge from either the 2 or 10 o-clock. Moves smoothly between those numbers. But feels like I’m hitting something trying to get to the 12 (TDC). Is it hitting a piston maybe? How do I correct this? The two pulleys up top are centered. So why am I having this issue?
