Retirement tax questions

Thank you very much; this is helpful! 

A question for clarification… 

In the event that in 2023 I pay via weekly paycheck withholding as much (or more) income tax as I did in 2022, does that satisfy requirement “C” and mean that I will not need to deal with the estimated payment on April 15, nor worry about underpayment penalties?  Or is that 100% of last year’s taxes figure something that’s paid *in addition to* my weekly paycheck withholdings? 

Just trying to make sure I’m understanding that properly.
