Congrats on your new guitar.

It doesn't sound like a relief issue so adjusting the truss rod probably won't cure it. It sounds to me as if it's a fret issue and/or the nut slot for that string isn't cut properly or combination of those?

As it's new to you I'd take it back to the shop where you bought it and, politely, insist on a proper set up.

Let us know what you find out.
