Rounding 401(k) amounts exceed the allowable limit by $1. Should I make any changes?

[d-n-kamel]

I made contributions to a traditional 401(k) and Roth 401(k) through my employer.  The amounts both came out to $xx.50 but when entered into TurboTax they were both rounded up to the next dollar.  When added together, they total $18,501 after rounding.  Should I round one of the numbers down so that they equal $18,500 like the numbers reported on my W-2? Or do I leave them alone, even though they exceed the limit?

You should round down one of the amounts.
