Challan details mentioned in the statement not present in the challan file imported - This error is seen while filing Q3 Return - can any one help

Dear Experts,
I have paid a contractor Rs. 150000 in April 2021 but I didn't deduct his TDS neither I had deposit the same to Goverment because I didn't had TAN number.

Please guide what to do ?

I want to know that, if I deduct any TDS of a professional person (Honorarium Payment) what will be that, a company deductees (20)or a non-company deductees (21).

Dear Sir,
Good Morning.
I did go through the reply / response by you with reference to the loss incurred on delisted shares LANCO Infra in which I have also invested in the years 2015-16 and 2018-19. I understand that I could incorporate the full amount invested by deducting only one rupee from the same.

I did invest/purchase LANCO for forty thousand rupees in FY 2015-16, thirty thousand rupees in FY 2018-19. The last traded date (with price) of LANCO shares in BSE is 12-September-2018 (Rs.0.42) and later shares are delisted/suspended.
So if I am incorporating the loss now for the assessment year 2020-21 (FY 2019-20), whether it is applicable as LTCG or STCG?

The one rupee present value to be considered as on Delisted date?
OR
Any other (applicable) dates?

I had a consultation last year (2020) with an auditor (in our area) who informed me that I could not book the loss in delisted or suspended shares and so I did not incorporate those invested amounts in ITR so far – for your information please.
Waiting for your valuable comments.
Thanks
