Is there a KiCad symbol and footprint for the SN74HC682N?

Yes. The symbol is EasyEDA_Cloud:SN54LS682J and the footprint Package_DIP:DIP-20_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74HC682N?

PDIP-20, with 20 pins. Its footprint is drawn on this page.

Where is the SN74HC682N datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the SN74HC682N?

JLCPCB lists it as part C2871294, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SN74HC682N?

Parts like it in the library: the SN74LS688N by Texas Instruments, the DM74ALS520N by onsemi, the 74HC688P-E by Renesas Electronics and the 74HCT688P-E by Renesas Electronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
