Table 4A & 4B of GSTR9

I have a doubt regarding Table 4A and 4B of GSTR9.

Suppose, I have made some mistake in one of my GSTR1 and showed the taxable value to be higher than actual value, but the taxable value in GSTR3B is correctly entered by me. Which value will be reflected in GSTR9? R1 or 3B value.

e.g. Due to a mistake in January,2021 GSTR1 by Rs. 2 lakh, my total supplied taxable value becomes Rs. 27 lakh. But my actual total supplied taxable value was Rs. 25 lakh. This Rs. 25 lakh was correctly entered in GSTR3B. Which one will be autofilled in Table 4A of GSTR9 suppose if all my supplies are made to unregistered persons? Or in Table 4B if all my supplies are made to registered persons.
