Roth contributions prior to 2023 which include regular contributions and a rollover Roth

[mracc1989]

As the subject states, I have funds in a Roth IRA which include original contributions I made over a number of years which I did enter to Turbo Tax (TTax). A few years ago when I retired I rolled over my government employers Roth 453 plan dollars into this same original Roth I have. 2023 is my first year drawing distributions from this combined Roth IRA.

Question: TTax put a number in a field for "Roth Contributions prior to 2023". I presume that number is an accumulation of what I entered myself over the years for the original Roth IRA. But, it does not include the rolled over Roth 453 plan contributions. I never tracked Roth contributions each year for the original or the rolled over plan so no way I have that number.  Here is at least my most concerning question(s). 

Since the number TTax has for Roth contributions prioer to 2023 is too low and if I leave it at that will TTax limit future non-taxable withdrawals to that number TTax entered in that field? If so, should I guess (educated) at what the number should be and enter it in that field so as to allow for future Roth withdrawals to be non taxable? Or does it even matter what that number is? If so, why is it there then?

I know this is a bit wacky but real life sich.  Thanks for any help, much appreciated.

At the time of the distribution, were you over age 59½ (code T or code Q in box 7 of the Form 1099-R) and made your first Roth IRA contribution for some year prior to 2019?  If so, your Roth IRA distribution is a qualified distribution with no need to know your contribution and conversion basis because qualified distributions are tax free and not reported on Form 8606.  Qualified distributions are included on your tax return only on line 4a of Form 1040, not on line 4b.
