the deceased is my son. i followed turbo tax< and the IRS keeps rejecting it.
Sorry for your loss. Some things you need to be aware of here. When someone passes, if the entity handling the final affairs (I"m talking about the funeral home here) has done their job, one thing they will do is to notify the social security administration of their passing. The SSA will mark that person's records accordingly, as they wait for any claims to survivor benefits if applicable.
Every year, around the Dec-Jan time frame the IRS pulls tax filer information from the SSA computers. So if your son's SSN was marked as "deceased" by the SSA, the IRS knows they've passed. The IRS will then permanently lock the SSN of the deceased so that it can't be used fraudulently. The most common error returned in that case when you attempt to e-file is "SSN LOCKED". But that's not the only possible error, be aware.
Therefore, if the IRS has locked the SSN you have no choice but to print, sign and mail the return to the IRS. If a refund is due on that return then you'll also need to include the IRS Form 1310 which you can get at https://www.irs.gov/pub/irs-pdf/f1310.pdf
Supporting documents to verify your claim to the refund may or may not be needed also. It depends on to many factors to cover here.
