<prompt> Human: Hello - I have a question on contribution limits for retirement accounts.Can I put 18k in my 401k, 5,500 in my IRA, and 5,500 in a Roth IRA?Also, how do you set up an IRA if I already have a 401k through my employer?Thanks for any help you can provide.  <response>: You can only put 5500 total into IRAs of any kind. You can set up a traditional or Roth IRA through a broker. Vanguard is a popular one with low fees.
