Quarterly submited VAT details including vat Amount

Dear Sir/Madam,

I would like to ask question on VAT return due to an unintentional mistake.

The correct taxable sales amount (before VAT) was SAR 13,368.59, but by mistake I entered the amount including VAT, which was SAR 15,373.88.

Similarly, the correct taxable purchases amount (before VAT) was SAR 18,487.40, but I mistakenly entered the amount including VAT, which was SAR 21,260.51.
I have now realized that, while filing the VAT return on the ZATCA portal, I entered the amounts inclusive of VAT instead of the taxable amounts before VAT. This was a genuine human error. I did not gain any benefit from this mistake, nor was there any intention to provide incorrect information or violate the VAT regulations.
How can i correct that without any penalty.
