I have submitted a tax return  twice and it has been rejected both times. error-FED_Taxable _inherite. Says a potential issue with calculation. This distribution is not an inherited IRA. However it does have a basis of which I have completed 8606. I have went over it many times to see if I had checked an inherited box. I can't find anything. Any suggestions or help would be greatly appreciated. I have done this client's tax for many years with the basis and never had an issue. Thanks.
