Traditional (pre-tax) 401(k) contributions and Roth (after-tax) 401(k) contributions do not count toward your annual IRA or Roth IRA contribution limits.
You can contribute to an IRA or Roth IRA and a Traditional or Roth 401(k), as long as you meet the income limits for contributions to IRAs and Roth IRAs.
See https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-ira-contribution-limits
However, contributing to a Traditional or Roth 401(k) may reduce the amount you can deduct from your federal income taxes for your contributions to an IRA or Roth IRA depending on your income levels.
