I'm a little late to the party at 26yrs old and was just finally landed a great job that matches for my 401k. I see the ideal percentage to invest into then from my check is 15% then to move to 20%. Does that mean 8% Roth and 7% 401 now then 10% into each later? I apologize if this is a dumb question. I never got into finances and I'm neurodivergent so I often need rather direct instruction
