Looking for advice on my Roth IRA portfolio

I’m 20 years old, currently putting $60 a week into my Roth IRA currently at $1,000. As of now, I am investing in VTI, VXUS, and QQQ. Considering selling my shares and going either: 1. 60% 40% in VTI and VUG. 2. 60% 20% 20% in VTI, VXUS, and VUG. Are either of these options preferable to each other and my current portfolio? Does it really matter that much right now? Any advice helps, thank you!
