Narrative:

We were given instructions to hold 5 east of the deale intersection at 10;000 ft approximately 5 miles from arriving at said intersection. It was programmed and put into the FMS erroneously to 5 miles west of deale. As we approached the point; I recognized the error and started a turn approximately 2 miles late while the pm reprogrammed the FMS. ATC noticed and instructed us to continue the turn and to reprogram to the original instruction; which was 5 miles east.on the outbound leg; turning inbound; I noticed we were on a collision course with a 737. ATC noticed it too and gave us an immediate left turn and descent. I complied instantly by disengaging the autopilot and rolling the aircraft left and initiating a dive. Within 2 seconds; the TCAS RA went off and instructed us to climb. I did not hear the RA amidst the commotion and radios; nor did I see the vsi (vertical speed indicator); as I was heads up ensuring separation from the other aircraft. The captain saw the RA on the vsi; took control and began a climb. We climbed to approximately 11;000 ft to clear when we then got a TA from a different aircraft that was behind the original at 11;000 ft. We continued the left turn; informed ATC of the RA and were given vectors and descent to 10;000 ft. The flight henceforth was without further incident.
