You may find it necessary to delete some 1099-B worksheets or Capital Gains worksheets which feed the 8949 form and subsequently the Schedule D form.  Don’t be fooled by leaving a 1099-B worksheet or Capital Gains worksheet in the return which appears to be totally unrelated to the 8949 form you are trying to delete.  Save your return to a new file name and then start removing the worksheets until you hit upon the worksheet that is recreating the 8949 form you are trying to delete.  Once you have identified the worksheet recreating the 8949, you can selectively delete it from your old return file name and recreate anything else needed.  Hope this helps.

Using Home and business 2018 on a mac. Need to delete a duplicate form 8849. When I follow the above, I et a box that asks whether I an sure I want to delete and says the data connot be reconverted, I have no idea what reconverted means and cannot find a mmeaning for it anywhere. However since it is a duplicate transaction with an incorrect basis I do not care if the duplicate data "cannot be reconverted". So I say yes I am sure . The form then deletes for 1 second and magically reapppears. This return is for a client, it is late as heck and has over 400 transactions. There are going to be errors in entering the intial data and duplicate forms will be generated. We need to edit in a less cumbersome way. Please advise

Form 8949 is created automatically from the schedule D entries.  Schedule D probably need to be deleted first to delete the 8949 form or it will just reappear.
