I speedran this game on PlayStation and wondering if I should put it as a different platform or if I can’t participate at all

Turnip Boy Commits Tax Evasion was only added on Playstation very recently, and since there were no PlayStations runs submitted before yours, the thought didn't immediately cross the mind of people when it was added on PlayStation, it should be added soon.

(When it is done I'll edit the console you played on)

As a side note, Playstation has been added as an option in the mean time
