Retirement tax questions

Thank you. I've checked all the forms I saved but did not see 8606. I used TurboTax desktop software and entered information based on1099-R. On the tax form (Married filing jointly) entered '0' for Traditional and Roth IRA contribution for both. Could that be the reason?

 Can I file amendment (corrected1040 with 8606) while filing 2025 taxes /Turbotax or from 2024 taxes?
