I am new to networking so I apologize if this is a bad question. I am going through my house and putting connectors in all my rooms that were wired for cat5e and I noticed that some rooms have cat5e cable with TIA 568-c written on it. The color diagrams on the connectors I purchased only list A and B connections. Am I able to put these connectors on TIA 568-c cat5e cable, and if so do I wire according to A or B? Or do they require a different kind of connector? Thank you

I assume the markings simply mean that your cable itself was made to conform to various other parts of that standard.
ANSI/TIA-568-C.0 does not define any new pin assignment. It says:
5.3.3.2 Eight-position modular jack pin-pair assignments
Pin/pair assignments shall be as shown in figure 4 [T568A] or, optionally, per figure 5 [T568B] if necessary to accommodate certain 8-pin cabling systems. The colors shown are associated with 4-pair cable.
NOTE - The choice of pin/pair assignment designation can be customer specific. For example, see US Federal Government publication NCS, FTR 1090-1997 for US Federal Government installations.
So you're still supposed to use the same T586A/B wiring. Technically the choice of colors is all up to you, the signal does not care (although paired pins must forever remain paired, otherwise Ethernet wouldn't work).
Using TIA 568-B's wiring and color code for TIA 568-C works fine for me for ethernet without any issues.
