Retirement tax questions

I did not enter them myself, once I added a few details from my W-2 the rest was imported automatically. My contributions were coded as AA for Roth 401(k) contributions. I did not put anywhere close to the $22,000 limit according to both my W-2 and HR department, but TurboTax is reading my contributions as IRA contributions where I would have surpassed the $6500 annual limit.
