The ID of the inner bearing simply hung up on the accumulated corrosion that is just outside the bearing track. This is somewhat common and does require some force to "press" the bearing through this area. It's not easy to tap the front rotor due to the heat shield, but if you did it lightly and did not jam the rotor/bearing combination at an angle, you would not have damaged the bearing.
This situation tells you, however, that you need to polish the spindle with some very fine emery cloth (I like 400) prior to reinstallation. Otherwise the same problem will occur when you attempt to seat the newly repacked bearing. The clearances between the bearings and the spindle are very tight..........on the order of .0005".
The inner bearing typically gets damaged when the mechanic removes the inner seal to remove the inner bearing. If any prying is done against the bearing, you will damage it.
You did remove the inner bearing for a proper repack...........right?
