What are classed as discrepancies when bank account checked by uc

[Meworried]

I have to give uc 4 months of bank statements what gets flagged or questioned as my ex partner gives some money for our son randomly when he choses my family member also gives me some cash every so often ect also heard of some people saying vinted and ebay transactions questioned? i just have really bad anxiety very ill (this not helping) and would like to prepare / know how to handle questions or what to expect say for best. Thank you.

They would be looking for savings over £6K. For example an inheritance that hasn't been declared.

They might just want to check activity to prove you are a genuine claimant. My friend went onto UC during COVID so they did retrospective checks he was who he said he was as there had been a lot of fake fraudulent applications made at that time.

i have to give universal credit 4 months worth of bank statements for a review ,do they ask / allow you to use sites like vinted or clearpay im so nervous about what type of questions will be asked or purchases scrutinised? although i dont think i do anything wrong (certainly not on purpose) my ex sends money for our son- amount £300 pm or less every so often not consistent, ive been told that wont effect my uc because its known as child maintenance? i still worry. My family member sends me money also every now and then as gift and in return when i can i send her cash for gifting and giving me board or food ect she doesnt officially charge rent or that so i try give back what i can. My health condition aswell as my physical at all time low with this all i actualy have surgery next week also :( i need some help or suggestions. I have to submit my statements in 1 week and phone interview after. Thank you.
