I dont have TIN, VAT, OSS numbers and I am not business, so I want to know what
information should I give so my store will remain open.
There’s an official help here: https://taxation-customs.ec.europa.eu/online-services/online-services-and-databases-taxation/taxpayer-identification-number-tin_en#tin-by-country
The document is available in Polish.
There’s pictures of your official documents (passport, ID card, taxes declarations…)
where you can find your Polish equivalent of a TIN.
