I inherited a Giant TCR Advanced 1 from my deceased brother. I know that he purchased it around 2017 or 2018 but don't think that it was the current year. I have been googling images for 2014-2018 and am not able to match any images to the bike. I also tried to register it on the Giant website but keep getting an product not found error. The barcode is F/N GC7A118 and the plate matches with GC7A118. Does anyone know what year it is, or a reliable site where I can look it up? A few years ago I used this method to identify the year of an old Trek.

Thank you!
