How to enter the data of income tax in Sage Accountant

Suggested

I am using Sage Accountant to prepare for the first quarter MTD of income tax for my client. 

Following the instruction, Sage Accountant has been connected to HMRC and MTD authorised.  

I have two types of clients, one is solo trader, the other one is landlord. 

I created Self assessment of 2026/2027, then add MTD tax year successfully. 

Regarding solo trader, Opening tax year, choose self - employment business. It says You cannot access this page on Income and Expenses tab. But I  am admin of Sage Accountant. 

Regarding Landlord, on income and expenses tab, it shows No income recorded. But I cannot find a place to enter the data. 

Anyone can help me about those issues. 

Many thanks
