If you're new to Java, learn Java before you start modding, the error you're getting means your code isn't valid. Also I hope to god you aren't hoping on making modding tutorials as your first experience in modding.

Are you new to Java though?

Really old Minecraft versions are no longer supported on this forum. Please update to a modern version of Minecraft to receive support.

Dependencies that have names ending in _mapped_[stable/snapshot/official]_[Mapping Version] are NOT hosted anywhere, they are generated by ForgeGradle on the fly and inserted into Gradle through a fake repository, when one of these dependencies is reported missing it is a sign that errors occurred generating them. Please look higher in the Gradle log for answers.

Last thing I can think of is deleting C:\Users\wyatt\AppData\Roaming\.minecraft\versions\1.16.5\1.16.5.jar

User was banned for piracy. Buy the game.

Replace https://files.minecraftforge.net/maven with https://maven.minecraftforge.net, the server moved

Delete C:\Users\wyatt\AppData\Roaming\.minecraft\libraries\de\oceanlabs\mcp\mcp_config\1.16.5-20210115.111550\ and try again

Forge doesn't use Optifine, but Optifine is a rather invasive mod that overwrites a lot of stuff, here we see it removing or otherwise rendering unusable or invalid, a Forge-added method.

Provide the client's debug.log please
