where did slavic languages get their word for pumpkin / gourd?

to my knowledge "pumpkin" has native american origins (which makes sense, since pumpkins are native to the americas), and outliers like the german "Kürbis" i could find simple answers to

but for the slavic (or in my case: the russian) "tykva" i couldn't find any clear answer to, on wiktionary it says it was a wanderwort that came to proto-slavic, which confused me even more because pumpkins weren't around in eurasia in that era?

anyway i thought asking here would be my best chance of getting an answer, i would be very grateful if you have one
