Hi some transactions that were posted on credit card on Dec 30 is showing on quickbooks as Jan1st. How can I change this

Hi there, @vrajivind. 

Thank you for reaching out to the Community. It's my priority to help you sort this out. We can manually modify the transactions and exclude it. It could it be a duplicated transactions from QuickBooks. I'll show you how to exclude the transactions.  

1. Go to the Transactions menu. 
2. Double click the transaction that was posted on Jan.1st. 
3. Check the tick box to exclude it, and tap Save. 

Once done, it will appear in your transaction and under type it will show the Excluded. 

For additional information on this, I recommend the following article: Categorize and edit transactions in QuickBooks Self-Employed. 

Please let me know if you have other questions in QuickBooks. I'll be here to lend a hand. Have a great day!
