My husband and I received some unexpected money and we would like to each increase the contributions to our Roth IRA's for 2018 to $ 5,500.00 total per IRA. In the taxes we filed we reported 1,500.00 and 1,375.00 for the amounts contributed to these IRA's during 2018. To make an increased contribution, do we need to amend our tax returns, and if so at what penalty with the IRS and what charge from turbotax. Thank you!
