Hi,
EIGRP does not use invalid timer/max age like OSPF. The route gets removed only if it receives an update to that effect from the neighbor who originated the route or if the neighbor itself goes down.
Here's a topology capture of a route and the actual route in the FIB. It only tells you the age of the route in the FIB and that's it.
R2#show ip eigrp top 1.1.1.1 255.255.255.255
IP-EIGRP (AS 1): Topology entry for 1.1.1.1/32
