Final 1040

The form 1040 should include all income paid up to the date she died.  It must be filed under her SSN.  If the IRS has blocked the SSN to prevent identity theft, you must print and mail the return.  You also must sign the return, which you can't do electronically when e-filing under her name.

The form 1041 would be used for the estate tax return, if the estate has taxable income after her death.  It must use the estate EIN.  This return would require Turbotax Business to prepare, which is only available as a download or CD for the PC, there is no Mac or online version. 

Thanks to all the responses.  You have definitely helped me solve my situation.

When someone passes away, and those handling the final arraignments actually do their job (usually the funeral home) the Social Security Administration is notified of their passing. In turn, the SSA notifies the IRS. The IRS then locks the SSN of the deceased person so it can't be used fraudently. One (of many) errors you will get when attempting to e-file a return with a locked SSN on it is "SSN LOCKED". When that happens, that's your indication that those who handled the final arrangements actually did their job. You have no choice but to print, sign and mail the return.
Sometimes, you might have to include the IRS Form 1310 with the mailed return if a refund is due on it. That form is not included in TurboTax. But you can print a blank one to file out and sign at https://www.irs.gov/pub/irs-pdf/f1310.pdf.  Additionally, it may be necessary to include in your mailing any documentation that allows you to legally sign the return of a deceased person. Something like a court document appointing you as the administrator of the person's estate may suffice.

This tax return is for my son he is disabled and asked me to help him.
