For the most part you can ignore, for income tax purposes, what goes on
inside of your IRA. There's a very few exceptions, including buying
securities within an IRA and thereby creating a wash sale in a non-IRA
account.
In your example, in box 20 of the K-1 you could just possibly have
Unrelated Business Taxable Income. If over $1000 you need to notify
your IRA custodian, who will have the responsibility of filing a form
990-T and paying the resulting tax and charging you for the work.
The tax comes out of your IRA.
In the years I have been seeing these schedules I have never seen
one approaching that much UBTI, but I might just lead a sheltered life.
