Narrative:

I had mistyped an intersection (wooly) into my GPS route of flight cleared by ATC returning to hef. The intersection I typed in (wolly) was northwest of my intended and cleared route of flight after balance VOR instead of southwest. I was practicing hand flying this particular leg of my flight that morning and after departing and following runway heading directions while climbing successively to 3;000 and then 6;000 feet; had been cleared to wooly. I was queried once by ATC as to whether I was flying direct to wooly; which I incorrectly confirmed after viewing the GPS. Approximately one minute later; I was queried again by ATC and it was at that time that I noticed the discrepancy when comparing the GPS indications to the indications on my ipad using foreflight and an IFR sectional. The controller identified the direction I should have been heading which I turned to while entering wooly in the GPS and heading directly to wooly. I then complied with additional vectors to facilitate my return to hef.my mistake began with my landing and requesting an immediate taxi back and my clearance back to hef where I began my flight that morning. I was taxiing and reprogramming the GPS after receiving and reading back my IFR clearance from the tower controller. I should have waited until stopping at the hold short line or the run up area to program the next segment of the flight as I was flying single pilot that day. In that case I could have taken greater care in entering the flight plan in the GPS and checking it as well. Taxiing the airplane and programming the GPS compromises safety and better management of my responsibilities would have kept the navigation error from happening.

Title: BE36 pilot reports incorrectly programming his GPS after receiving a clearance while taxiing single pilot. Waypoint WOOLY is incorrectly entered as WOLLY; resulting in a track deviation. ATC detects and corrects the error.

Narrative: I had mistyped an intersection (WOOLY) into my GPS route of flight cleared by ATC returning to HEF. The intersection I typed in (WOLLY) was northwest of my intended and cleared route of flight after BAL VOR instead of southwest.
