Inherited IRA created at company A. Then I transferred that to Company B as an Inherited IRA. Then, I pulled 30%

My mother passed away in 2025. Since I am the only remaining IRA beneficiary, Company A created an Inherited IRA in my name.  I then did a Direct transfer to Company B, as an Inherited IRA.  Then a few weeks later, I withdrew 30% to give to my sister-in-law as her part of the inheritance. Taxes were withheld at my request by Company B.  Question: Is there a time limit before I can withdraw money from the transferred inherited IRA? I am aware of my Inherited RMD requirement, which should be satisfied by the withdrawal I took. 

Thanks
