I filed 2018 return with daughter as age 16 when she was actually 17. The Irs billed me for additional tax for the error but did not require me to amend my return or Tax Audit did it and did not send a copy. Now working on 2019 and I downloaded 2018 return into the software and everything is just like I sent them in April of last year with my daughter age wrong and not showing the additional tax i had to pay. What should I do?
