Most "line-in" inputs on sound cards are 1/8th inch stereo jacks. If you look at them closely you'll see two spring loaded "pin" contacts inside plus the "ground" ring (which is rarely the entire ring anymore. Now it's usually a plastic ring with a small hole for another spring loaded contact). Same thing as a stereo headphone jack, just wired to the "in" instead of "out" side of the sound card. A few higher end sound cards also include "rca" type connectors with individual left and right jacks, as well as optical (digital) inputs.
Even if you have the "rca" type plugs, you still shouldn't connect a turntable directly to them. The output from turntables is "weighted" differently than a "line level" signal. Either run the turntable output through a pre-amp or into the "phono" input on your stereo reciever, then run a "line out" from the pre-amp or stereo into the "line in " on your sound card. You can easily find adapter cables (try Radio Shack) that connect to the "rca" type line out connection on your stereo and the 1/8th inch stereo input jack on your sound card.
If your sound card has a microphone symbol next to the input, it is probably mono. Most desktop cards have both a mono "microphone" and a stereo "line in" jack. Most notebooks only have the mono "microphone" input. In that case you can get an external USB sound card to input a stereo signal.
