Hi isabel-peterman,
You are able to use the bridging tool to submit the figures which you have calculated on the Excel spreadsheet. The bridging software is available through all of our online products (SimpleStart, Essentials, and Plus) at no additional cost to the subscription. The tool becomes available once the Making Tax Digital connection has been enabled on the account. You can see more on the bridging tool on our community guide or post any further questions you may have below and we'll get back to you.
Thanks!
