Deceased taxpayer has a refund on final tax return and the trustee is a trust company with EIN.  The Form 1310 seems to accept social security number for a individual person claiming the refund and doesn't seem to accept EIN of a trust fiduciary?  So this mean I cannot e-file the final tax returns with an EIN.  I prefer to e-file but if the program doesn't allow it because of this issue.  Looks like I must paper file the returns.  Is there a solution to this problem?
