Can I deposit the $6000 catch up amount in my employer sponsored 401K in 2018 for 2017?
I am an employee with an employer sponsored 401k plan. I am eligible to contribute the catch up amount of $6,000 in addition to the $18,000 but did not have it withheld during 2017. I would like to make an additional deposit into my account in 2018 for 2017. Can I do this and where would it be entered in turbo tax?
