Retirement tax questions

The program doesn't seem to recognize that the amount in my W-2, box 12, labeled WW counts toward the $19,000 limit and not the $6,000 limit. I think I fixed this by not labeling the contribution as an IRA, but it seems unnecessarily confusing (and that's probably because of the tax code). I think TT could be more helpful in making clear that there's a distinction between a Roth 401(k) and a Roth IRA and how to apply the correct limit to contributions.
