Retirement tax questions

Thank you for these answers. I made non deductible ira contributions into a traditional ira from 2014 thru 2022. Never filed an 8606. Prior to 2014 i made deductible contributions. in 2024 i took my first ira withdrawal in 2024.  I would like to simply do a one time cumulative form 8606 catch up and include all prior non-deductible contributions in total on 2024 form 8606, line 1, would my basis on line 2 be 0 since there were no prior forms 8606 filed? TIA
