Yes, you cannot do day-trading (check definition from IRS or Robinhood) on F1-visa but the rest is typically fine. Robinhood will issue you a bunch of tax forms (usually 1099 forms) at the end of the year. You'll need to put in the info from those forms into whatever tax filing software you and/or your college uses. My college uses Glacier Tax Prep but if you're using TurboTax, I've heard there is an option to enter your Robinhood Account Info and all your tax info will get transferred! Once your Tax form is complete, you'll know whether you need to pay more tax or you'll receive a refund.
UPDATE: I filed using TurboTax this time (for the fiscal year 2020) and can confirm that Tax Info from Robinhood stock trading (among other apps) gets automatically transferred using your account details (you should verify afterward though). However, you'll need to use the paid version of TurboTax to file taxes related to Stock Trading :(. Robinhood gave a little discount on the paid version of TurboTax :)
