We have heard of a few reports of sites using the 2018 program and returns are not rendering any calcs. Essentially, this means the Summary/Print menu will not load, but is instead stuck in a loop trying to load. To break the loop, click Basic Information from the left-hand navigation menu and you can continue preparing the return(s). Note: Generating a PDF may not be available as a by-product.
Our development team is actively investigating.
