ERROR WHILE INPUTING DIN Number in ITR EXCEL UTILITY

I received Order of Condonation under section 119(2)(b) by the PCIT, Mumbai-20. I have been granted condonation under section 119(2)(b) – to revise my ITRs for previous A.Yrs. 2017-18, 2018-19, 2019-20 and 2020-21 to claim the refund in respect of TDS made for pension received. As per office of Pr. CIT, the order has been uploaded on the portal and I have been asked to file my ITRs under Sec119(2)(b). Earlier I have been filing my returns regularly online and have paid the taxes as payable.
While filing my ITRs under Sec 119(2)(b), when I try to input the DIN & Letter No in the box meant for it as under :
ITBA/COM/F/17/2021-22/1036954563(1)
for ITR1 – AY 2020-21, I get an error stating that Unique number/DIN cannot exceed 23 characters and I am unable to proceed AS THE DIN CHARACTERS IS 35 CHARACTERS ALPHANUMERICAL.
Please advise
