exporting transparent images from Procreate and in Illustrator it shows up with a background

Hi i am extremely frustrated, i have been trying to upload my artwork from Procreate with a transparent background to Illustrator. I have unchecked the bakcground layer and done everthing I could think of and no matter if it is a .pdf, .png. jpeg, etc. it ALWAYS shows up with a background. this is for an adverstisement and I have no idea why it is doing this and I really don't have time to pen tool around the objects at this point, i really don't have time to troubleshoot and wrestle with adobe and it's constant barrage of issues any longer. PLEASE HELP! I really don't understand why this is happening when i have done everything to make sure the background of my procreate illustrations is transparent.

the illustration is a bottle of tequila for an advertisement so it is extremely important that the backgraound stays transparent but now the liquid in the image doesn't look right because i suddenly have this white background that won't separate or import as transpartent, even as a .tiff file. PLEASE HELP! I really don't know what to do and I am absolutely desperate, i have been trying to figure this out for over 2 days now HELP!!
