Sorry for the confusion. We have our own company that is LLC. It's my husband and I with no other employees. So we had a financial institution set up 401K accounts for us a few years ago. We don't have a set payroll, just take it as "owner's withdraw" here and there. Also put money into 401K when we can. We were told we could contribute in 2019 before April and put it on 2018 tax return. Just wondered how we post it on Quickbooks.
