You can put a Total Contribution of $26,000 in 401K if you are over 50, so this is not an error.
$19,500 for a regular contribution, plus $6,500 'catch up' contribution.
The 'catch up' has to do with your age, not how many years you are with the company, so unclear what the $3,000 'catch up' you are referring to is.
