Newbie here. Looking to invest about 40K into S&P 500.

So I've decided to start investing. From what I've read VTI and VOO are the ones to buy. Looking to put in $40K and hold for 10+ years. However, unsure on when to go in timing wise with the recent bill just passed (BBB) and the upcoming tariffs. Any thoughts? I'm very new to all of this.
