Congratulations on the new property, Pamela! QuickBooks Online (QBO) UK uses the term Tangible Assets instead of Fixed Assets because it aligns with official UK Financial Reporting Standards (FRS) required for HMRC.
To proceed, simply select Tangible assets from the Account type dropdown. You can choose Buildings for the structure or Other Tangible Assets for the land portion and hit Save. Once done, this account will act as the Fixed Asset category you need.
You can refer to this article for additional information: Choosing the right account types in QuickBooks.
Also, I highly recommend consulting with your accountant. If you don't have an accountant, you can find one here in our Resource Center.
Please let me know if you need any more help getting these accounts set up, or if you have any questions.
