Narrative:

I was originally given sbz alb V123 haarp direct hpn. When I programmed my GPS I inadvertently put in V157 after trgsa intersection which took me towards ign instead of on V123 which turns at trgsa towards cmk. About 10 mi past trgsa; ZBW inquired if I was still on V123. It was at that point that I realized I was on the wrong airway and apologized. Center cleared me direct to cmk VOR and that was it. In the future; I will exercise more caution and care in programming the GPS and reading the assigned route off of the en route chart.
