<prompt> Human: Not that Im complaining! Its odd that I only contribute 600month yet I had a surprise credit to my account thats greater than all my 2014 contributions!  <response>: Log into or call your 401k provider and look for recent transactions. Or on Mint, click on the 401k account. It could simply be a transfer within the 401k, and Mint usually hides those from Transactions, but maybe it got mis-classified as income.
