What is the combined (traditional and Roth) maximum IRA contribution limit for 2019? Turbotax is showing $6000 but IRS states $19000. Please, what is the correct limit?

IRS website - https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-ira-contribution-limits

For 2020, your total contributions to all of your traditional and Roth IRAs cannot be more than:

• $6,000 ($7,000 if you're age 50 or older), or
• your taxable compensation for the year, if your compensation was less than this dollar limit.

For 2019, the limits are the same as 2020.

Edited answer to remove incorrect IRS website.  Should have read - https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-ira-contribution-limits

The $19,000 limit applies to qualified retirement plans like a 401(k), not to IRAs.  The limit for IRAs is $6,000.  For those age 50 or over, qualified retirement plans also allow a catch-up contribution of $6,000 while IRAs only allow a catch-up contribution of $1,000.

Make sure that you enter amounts shown in box 12 of a W-2 only in box 12 of TurboTax's W-2 form, nowhere else in TurboTax.
