T1-OVP conundrum

Client rec’d NOA for 2019 return. Shows overcontribution, room for 2020 is -13k. 9k contributions mar '19 - feb '20 (reported on 2019 return) and some additional in mar-apr 2020 (client has biweekly PAC, now stopped). I have been able to complete T1OVP for Mar '19 to Dec '19 using RRSP deduction room or 2019 reported on NOA. How do I deal with period from Jan '20 until now? What do I use as deduction limit for this period? Any help appreciated. Note, client is member of RPP (PRPP).

I meant to say RPP (not PRPP).
