Is this Enterprise location the closest to Amtrak’s Sacramento station?

Yes..u can walk...but request a pickup....

Yes, and they will pick you up and drop you off at Amtrak, no extra fee.

Yes it is

Absolutely

Very close

Fairly close. Take Sac RT light rail from Sacramento Valley station to 16th Street station, then walk north of 16th to N Street. --- Reverse directions: light rail train (Downtown) bound for return to Sac Valley station. (Do not board Watt I-80 bound train!) Bon voyage!
