Investors & landlords

I have the business desktop software.   I can get the form in the software, b ut there is no step by step instructions for the form.    Also when I go to the IRS website to register the project I have gotten system errors when I go to submit the project and get a number that is needed on form 3468.  I have been getting that system error for three weeks.   It says to come back and try later.  I have to file the 1065 by the 15th and keep hitting roadblocks on this one.
