If your site works both IDT case work and injured spouse case work, do not reassign the case. The case should be retained and worked within your site.
You do have the skill set to resolve the case – Take all necessary actions to resolve the IDT issue following normal procedures. Use Hold Code (HC) 4 on your adjustment or TC 570 with credit transfers to hold the resulting credit. Then open a new CII case with Category Code "DMFC" , Program and Function Code "710-97140" , and "Priority 2" . Resolve the injured spouse claim
(15) Presidential Election Campaign Fund (PECF)
When the valid return reflects yes to PECF and the invalid return did not, see IRM 21.6.7.4.12, Presidential Election Campaign Fund.

(17) Valid taxpayer has not filed
Determine if the valid taxpayer has a filing requirement and address unfiled returns, if necessary. See IRM 25.23.4.17, Determining Tax Liability/Form 2209 Instructions.
(18) Non-Streamline
Research CC NAMES to determine if the taxpayer was previously assigned an IRSN.
If an IRSN was not assigned, follow local procedures to obtain an IRSN.
Once an IRSN has been identified, establish the entity with TC 000 or update the previously established account if current information for the IRSN taxpayer is available. See IRM 3.13.5.117, Establishing a New Account (TC 000). If a valid address cannot be identified, use a Service Center (SC) address. See IRM 3.13.5.66, Campus Address Used Only When Taxpayer Address is Unavailable.
