Unfortunately your FG reading is off since you already added the sugar so for all you know it's closer to the desired FG then your reading.
How long did it ferment?
AG or Extract?
Temperature of mash?
Temperature of fermentation?
At 1.090, 1.027 would be a reasonable FG so it's not that far off. Was the OG higher than expected?
Lots of questions to answer, for all we know it could be done and since you already racked, package it
