6K in Roth IRA, then what’s next?

I’m 31 and just opened a Roth IRA account. I contributed 6k and then… what’s next?

Using Fidelity & I bought DIS stocks for $1k… just because. TBH, I don’t know what I’m doing. Is this something wrong ? Where should I invest for Roth?

Please, any wise advise would do.
