Get your taxes done using TurboTax

Ok. but I don’t know what my final AGI is until I’m filing my taxes, which is after I’ve already contributed… I might find myself 

somewhat close to the limit (or at least at the range the contribution would have to taper off) so to keep an eye on it do I use my “Year to Date Net Pay” on my paycheck as guide to ensure I’m below the income limit  (bc the AGI would be further adjusted from that?)
