Against the 2017 Corolla: the two manuals do not print the same part types, so there is nothing to compare line by line.
Against the 2019 Corolla: the two manuals do not print the same part types, so there is nothing to compare line by line.
The 2018 Corolla belongs to the 11th gen sedan (E170), which began with the 2014 model year (MY2017 refresh (LED headlights standard per Toyota; not detailed on Wikipedia)); generation dates. Parts often carry over within a generation, but the manual for your exact model year is the one to trust.

What the manual does not print
The 2018 Toyota Corolla owner's manual does not list wipers, battery and filters sizes; for the battery, read the label on the battery fitted to the car, then check the size against the BCI group chart; for wipers, measure each blade end to end and buy the nearest whole-inch size.
Buying the parts for a 2018 Corolla
- Small bulbs: this manual names 5 replaceable bulb positions. Wedge bulbs such as W5W and 194 differ from twist-socket bulbs such as 7443 or 3157, so match the full number, including suffixes like NA (amber).
- Oil: ILSAC GF-5 SAE 0W-20. Use the grade printed for your engine if the manual lists more than one.
