Clarification regarding itc of trans1 and filing of gstr3b

I am eligible to get ITC on stock as on 30-6 but since the TRANS1 form is not available on GST Portal, the same was not filed. To avoid the last days rush in filing the return, I have already filed by GSTR3B return. The TRANS1 form will be available on portal from 21st Aug. What to do? Will I be able to avail ITC even if I have already paid the amount of tax liablility arising while filing the GSTR3B return.?
