I'm sorry for your loss.
If your husband passed in 2019, then you still get to file a joint return and claim his standard deduction for the entire 2019 tax year. Therefore you will report the income *exactly* the same way you did in 2018.
I can't get more specific, because you provide no particular's about the trust. For example, if the trust owns the rental property, then the income is reported on the 1041 trust return.
Now I would expect a trust to have it's own EIN. But that depends on the type of trust. Since you refer to the trust as "OUR" trust, there's no way of knowing if it's a revocable trust that became irrevokable upon the passing of your husband, or if it remains revokable until both of you have passed...... assuming that you and your late husband are the only owners/trustees of the trust.
Trusts can be very complicated - especially a joint trust. So that's something that if you're not sure, I would highly recommend you seek professional help... preferably from the entity that drew up the trust for you two if possible.
